Spark plugs for a prevortec 350

Knowing that I use NGK BR6FS and unable to get them till next week,would it be ok to use AC R44T Till I get the NGK's in?

That's the Same Plug as the AC MR44T,..... Only with a Steel body instead of Alloy........<br />Merc. calls for the MR43T......Is that Hotter,.. Or Colder..???<br /><br />Shouldn't be an Issue in the Short Term.......

R44T is one step hotter then the R43T.I was told that same plug goes up to R48T,which is the hottest.(Is that a word,hottest)?Anyway,I was also told that GM used R43T for trucks and that R44T was used it some cars.All this from a parts saleman.<br />That is why I was asking if I could use the R44T's till I get some NGK BR6FS plugs.<br />Yesterday I had fired up my port engine.After setting the valves,adjusting the carb a bit,she sounded good.<br />Now all I have to do is finish putting the rest of my boat back together.She has been dry dock sents last September.

AC R44T.......okay until you get new ones.<br />Not a problem, but 43MT are just fine in my boat, a 25ft/350, never tried NGK's, because AC does not give me a problem
